The Children who turned blue without cabbage

In 1951, The Lancet reported the odd case of siblings who would turn blue unless they regularly ate cabbage. It turned out that the kids suffered from a genetically caused deficiency of ascorbic acid. Knowing this freed them from a lifetime of having to eat cabbage. Though they had to take ascorbic acid supplements instead.

I'm pretty sure that the relevant Lancet article is "Familial Idiopathic Methæmoglobinæmia" (Apr 28, 1951), although I haven't been able to find a non-paywalled copy of it to confirm this.
